Connect an AI-built app to a custom domain

Your customer generates an app and publishes it. CustomDomain™ connects their own domain right then, root and www included.

For founders, onboarding product managers and AI agent builders at builders such as Lovable, Bolt and v0.

Finds the providerReads the nameservers and names the DNS provider, even when the registrar differs.
Checks firstFlags AAAA, CAA and records in the way before anything is written.
Writes the rootUses the provider's ALIAS-style record, or A records where none exists.
Checks each recordMoves to live only when every record resolves to its expected value.
Serves HTTPSGrowth and up The edge issues the certificate on the first HTTPS request.
LimitOn Starter and Startup, domains point at your servers and you serve TLS.

Common questions

How do customers connect a custom domain to an AI-built app?

They type the domain in the widget inside your publish flow. CustomDomain™ finds the DNS provider, writes the records where that provider allows it, and shows the exact rows where it does not.

Can DNS be set up automatically for an AI-built site?

At providers with an automatic path, yes: a sign-in with the provider, the provider's own template or a scoped API key writes the records. Elsewhere your customer adds the exact rows, and each one is checked.

Why does a custom domain on an AI-built app stop working?

Usually a leftover record: an AAAA sending visitors elsewhere, a CAA blocking the certificate, or a proxy left on. Hourly drift checks report records that change after the domain is live.
